Full screen issue

Hi,

Thank you for reaching out! Would you mind reporting that on Bugzilla, Mozilla's bug tracker, so that the developers could take a look? We'd also appreciate you sharing some more details:

• Your OS version
• Your Firefox version
• Whether you use several monitors
• Whether the issue persists if you toggle hardware acceleration in Firefox settings

If you don't feel comfortable with filing a bug on Bugzilla, just let me know, post the necessary info here, and I'll create a bug for you.

Hello,

my OS system is Win 11, I have 145.0 version I use 2 monitors, but on both is the same problem.

Could You report this for me?

Its really annoying. I would be great for the help.

Best regards

Yes, we've already reported it and it's being investigated. For now you can try to go to about:config and switch widget.windows.windowsappsdk.enabled to false.

ITS working, but first time i use full screen its still cut. When i Close fullscreen and use it agaon it works.

Hi there,
